Customer Service Mode (CSM)
Purpose
The Customer Service Mode shows error codes and
information on the TV's operation settings. The call centre can
instruct the customer (by telephone) to enter CSM in order to
identify the status of the set. This helps the call centre to
diagnose problems and failures in the TV set before making a
service call.
The CSM is a read-only mode; therefore, modifications are not
possible in this mode.
How to Enter
To enter CSM, press the following key sequence on the remote
control transmitter: "123654" (do not allow the display to time
out between entries while keying the sequence).
Upon entering the Customer Service Mode, the following
screen will appear:
